gassolidity
I have a public view function that have a for loop inside of it, I put the loop inside the view function so I wont need to worry about the gas.
now my question is if I call the function internally from an other function that is not a view function will that create the possibility of high gas consumption (because of the for loop) ?
I think you may be alluding to the online remix compiler for Solidity. This will allow you to see easily how much gas a transaction to a function will need/spent.
If you execute a state changing function then inspect the details of the transaction you'll get more information. Please see the example below:
Here we can see trasaction cost & execution cost. Everything you need.
Hope this helps.
You don't pay gas when calling a view function. This doesn't change the fact it still has operations to do, which have costs, and thus are subject to the upper-bound gas limit on the block, as well as a time limit.
It's a bad idea to try to return an entire unbounded array, because the call will time out and you will not get anything.
What you could do is use a cursor like here, article which tackles the problem you are facing.

Even if you make a function a
viewfunction, you still have to pay full gas costs if it's being called inside a transaction. Suchviewfunctions are only free if called locally, not inside a transaction.So, yes, you will have to pay for full processing of the function if called from a non-view function (inside a transaction).
